Burned with a CNC laser from high-quality 1.5mm acid-resistant 0H18N9 sheet, resistant to all conditions in the exhaust system. The EGR valve plug is designed to prevent exhaust gases from entering the intake manifold. After installation, signs of damage to the EGR valve disappear. After plugging, the engine work culture is significantly improved (power and dynamics are restored) and it prevents future failures and deposition of carbon deposits in the intake system. & Nbsp
